Firstly a little background, I have been in the site a long time. Having first shared my wife of over 25 years with an old boyfreind of hers, ( my fantasy she indulged) she suggested, following severe long term illness and surgery, that I join SH to be the extra guy, to help a mature couple push their boundaries and experience new heights in sexual gratification. I have met many great couples here and made some long term friends. Work has of late restricted my ability to meet and play and I had been seeking some new partners, which isn’t easy for a single man. The advertisement I responded to was for a mature gentleman voyeur to provide a secure location to watch a couple. I corresponded with ( I will call them Clive and Karen to protect identity) for a few weeks. Asking normal stuff like pics etc. and responded with some excellent images of K. She was stunning. I had to check the ages in the profile again as I didn’t want to become involved with anyone too below my own age.(59). I run a business in London and have a showroom over two floors. It’s very private with access restricted but as it is on high floors with terraces can be overlooked. I had to find a way to create a private area where C & K could sit, like I was interviewing her, and she could allow me to see the view beneath her skirt. The entry phone sparked up right on time. It was C so I pressed to let him up. I suspected K would follow if he was satisfied I was OK and setting acceptable but to my surprise she was with him. We shook hands and they looked around. They were impressed with the surroundings and views of London and we opened a bottle of Prosecco and engaged in small talk about London, a City we all loved. After a few minutes more we sat to talk some more and they asked about my history on the site and they admitted not all great experiences for them. I complimented K on how she looked. Dressed in a smart well cut Business suit with skirt and jacket, white blouse and I hoped the flesh coloured nylons were stockings. I wasn’t disappointed. Within a few minutes I could see the patterned top and a little flesh above. The talk was quite sexy, sharing some scenarios and feelings of sex with partner plus one and C, who had been rubbing his hand over his sexy wife’s leg pushed the hem of her skirt up to reveal fist where the suspenders clipped the stocking tops and then her lace panties. They kissed and he massaged her breasts through her blouse and then undid it to reveal a bra that matched the panties. They were fully aroused, stood and embraced, kissing very passionately with K facing away from me. C raised his wife’s skirt over her waist to expose a peachy bum. He was squeezing it and asked me if I would like a feel. I moved towards them and asked politely if that was OK. She smelt fantastic and I ran my hands over her soft flesh. Squeezing softly and then gently slapping it. She seemed to like the attention and released C’s cock and started to wank him. Her blouse was removed and I was asked to feel her tits through her bra from behind. They were magnificent. A minute later I was told to remove her bra and did so, giving C access to suck K’s nipples which turned her in as she was being fingered by her husband. It was such an erotic sight. I suspect K had already climaxed and C could not be far away. My cock was straining in my jeans and I felt K’s hand exploring my groin and started to massage it though the material. She was very expert and the show the two of them were putting in immediately in front me and this stunning blond rubbing my now fully erect cock was mind blowing. K dropped to her knees and started to suck her husbands cock. It was a good size and she was expertly licking and sucking the knob while wanking the length in her beautifully manicured hand. Her skirt was still up at her waist and her bare breasts and stocking clad legs were an amazing sight. Next thing I knew my zip was being opened and my cock was freed and in K’s mouth being licked and sucked. I have never had such a beautiful woman blow me and it was everything I could do to hold back from Cumming inside her mouth and over her face. She took turns in sucking her husband and I for quite some time. It was a very horny scene. Finally she instructed us to wank off over her tits which took us no time at all, coating her magnificent breasts in a good volume of spunk. Fortunately not too much was spilled although there was evidence in her skirt and face. As the showroom was on view from neighbouring buildings K had me make sure the outside public corridor was clear and she made a dash for the ladies to clean up and wipe all our cum off her tits and freshen up. Anyone on the balcony of an adjacent building would have glimpsed a sexy lady, naked to the waist, streaking the length of our office with clothes in hand. C admitted that he was surprised and happy at how far the meeting went and that had I been pushy it would not have been the same outcome. I just felt totally guilty that I had put pressure on as I had to leave by 4pm at the latest and wished we had more time after to chat. No way had I expected any physical contact would take place let alone get my cock sucked and get to cum over the most perfect breasts. The moral is, be honest, respectful and not pushy and you never know what can transpire.
